Alvin's age + Elga's age = 84
2R + R = 84
3 R = 84
3/ 3 R = 84/ 3
R = 28
Elga's age is 28
Answer:
The middle between two numbers is the average of those numbers. So we add those two numbers together and divide by two. And the answer is (1 + 6) / 2 = 3.5
60 Are taken but the single is 1 and is that you
Answer:
30 or 120 /4
Step-by-step explanation:
a^p/q here p denotes power raised and q denotes inverse power or root. So, 60^1/2 denotes square root of 60 raised to power 1.
Answer:
y = x - 2 could not be the function equation.
Step-by-step explanation:
The function with an input of 3 has an output of 5.
So, y = 2x - 1 can be the function as y(3) = 2 × 3 - 1 = 6 - 1 = 5.
Now, y = x + 2 can also be the function as y(3) = 3 + 2 = 5
Again, y = 3x - 4 can also be the function as y(3) = 3 × 3 - 4 = 9 - 4 = 5
But y = x - 2 can not be the function as y(3) = 3 - 2 = 1 ≠ 5
Therefore, y = x - 2 could not be the function equation. (Answer)
